Newbie--used old e trex for simple stuff, now have Oregon 450. I have Win 7/64, having been reading and rereading this thread. Basecamp downloaded and seemed to install, but doesn't work. Sounds like installing My Trails is the way to go--except when I go to that page I don't see anything to install or download. Obviously I'm overlooking something, but I have tried to figure it out and read this forum and am stuck.
